This is a cool, old-fashioned thermodynamic hand boiler toy that is made of hand-blown glass. The liquid inside these beautiful boilers shoots up the tubes and appears to boil when you hold it in your hand. It makes an excellent stocking stuffer for the holidays, or a great classic desk toy for the office setting.
Note: This comes in various styles and colors. While we try and honor specific requests, we cannot guarantee what style or color will be sent to customers. Price is per each unit--picture shows four hand boilers for demonstration purposes only.
